Crow Wing County Geologic Atlas, Part A, County Geologic Atlas Series C-16, published by the Minnesota Geological Survey, 2004. More information and downloadable data for Part A available on the MGS ftp site.

The sensitivity rating model, based on the thickness of the protective layer between the aquifer and the nearest overlying recharge surface, is described in Figure 3 of Plate 9. Sensitivity ratings are applied as follows: Protective layer thickness - - Sensitivity Rating 0 to 10 feet - - High or Very High 10 to 20 feet - - Moderate or High 20 to 30 feet - - Moderate 30 to 40 feet - - Low Greater than 40 feet - - Very Low

The final raster was converted to a polygon shapefile.

Sensitivity interpretation was based on overlapping estimated time of travel ranges as follows:

Red - - Very High - - Hours to months Orange - - High - - Weeks to years Yellow - - Moderate - - Years to decades Light green - - Low - - Decades to a century Dark green - - Very Low - - A century or more
